REPELLERS FOR INDOORS

Indoor pest repellers have made a rapid entry into the market and they come with increasingly sophisticated electronics and secondary facilties such as doubling as a night light. There are two modes of action, Ultrasonic and Electro-Magnetic.

In our opinion, ultrasonic units are not 100% effective because ultrasound does not penetrate objects, so the units need to be strategically placed and numerous. Electro-Magnetic units work by changing the electro-magnetic field in your house wiring system and this change of wavelength of the field irritates rodents.

Mice are most susceptible to this magnetic field change and usually leave the property within a few days, however, if there are young mice, leaving may be delayed for up to three weeks. It is now claimed that these types of pest repeller will deter cockroaches, ants, and other crawling insects.
